Penny Martin Can you see this photo ?? taken by a friend in Orkney .. can anyone help with the ID

Marco Faasse One of the large hydromedusae, Aequorea forskalea (forskalea based on the number of tentacles being about the same as the number of radial canals). The banner of this group shows an Aequorea as well, but it's difficult to tell the number of tentacles relative to the number of radial canals in that picture.

David Fenwick Snr Can someone tell me the difference between Aequorea forskalea and Aequorea vitrina please. There were a few possible Aequorea washed up today at Sennen Cove, have never seen this pink coloration in them before, just white and glassy. Thanks.

Anne Bay-Nouailhat Hi David! Here are some identification distinctions between Aequorea forskalea and A. vitrina according to the synopses of British fauna about Thecate hydroid by P. Cornelius. "A. forskalea : up to ca 120 marginal tentacles, usually fewer than the radial canals but ranging from half to twice as many; radial canals 60-80; max diameter ca 175mm" and for A. vitrina :"60-100 marginal tentacles, three or more times the number of radial canals; radial canals 60-100; max diameter ca 100-170mm".

Anne Bay-Nouailhat You can report your sightings there : http://www.jellyfish.ie/ or/and there http://www.mer-littoral.org/formulaire-meduses.php

David Fenwick Snr Thank you for explaining that Anne, will endeavor to record them if I can positively identify them. Wish I'd have brought them home now, mid you they weren't in brilliant condition.
